I use those lens cap holder things, one of the best things I've ever bought. It has the sticky disc to stick to your lens cap, and a strap that goes around your lens...not only does it prevent you from losing your cap, but reminds you to put it back on if switching lenses.
put the lens cap back on. A lens may be on one of my cameras for a few hours or for a few weeks, but it doesn't need a lens cap until I remove it from the camera and return it to the camera bag. In between times, the lens cap stays in a specific pocket of my photo vest, so I'll be able to find it when I want it.
